| 摘要: 通过溶剂热法合成了3个锌的配位聚合物{[Zn2(bipmo)2(ipa)2]·3H2O}n(1)、{[Zn (bipmo)(5-OH-ipa)]·DMA·H2O}n(2)和{[Zn (bipmo)(5-Me-ipa)]·H2O}n(3)，其中bipmo=双(4-(1H-咪唑-1-基)苯基)甲酮，H2ipa=间苯二甲酸，5-OH-ipaH2=5-羟基间苯二甲酸，5-Me-ipaH2=5-甲基间苯二甲酸。用元素分析、红外光谱和单晶X射线衍射等技术对结构进行了表征。单晶X射线衍射分析表明，配合物1具有二重互穿的{44·62}二维网络结构，配合物2则是{65·8}拓扑的二维结构，配合物3却表现为二维的{63}拓扑网络。间苯二甲酸上5-位取代基的不同对最终的结构形成有重要的影响。此外，对化合物1~3的发光性质也进行了详细研究。 |

| Abstract: Three zinc coordination polymers, {[Zn2(bipmo)2(ipa)2]·3H2O}n (1), {[Zn(bipmo)(5-OH-ipa)]·DMA·H2O}n (2), and {[Zn(bipmo)(5-Me-ipa)]·H2O}n (3), where bipmo=bis(4-(1H-imidazol-1-yl)phenyl)methanone, H2ipa=isophthalic acid, 5-OH-ipaH2=5-hydroxyisophthalic acid, 5-Me-ipaH2=5-methylisophthalic acid, were synthesized under solvothermal conditions. These complexes have been characterized by elemental analyses, IR spectra, single-crystal X -ray diffraction, etc. Complex 1 shows a 2D 2-fold interpenetrating {44·62} network. Complex 2 displays a 2D uninodal framework with the {65·8} topology. Complex 3 reveals a 2D layer structure with {63} topology. The results indicate that the presence of a 5-substituted group in the isophthalate exerts a significant influence on the formation of the final structures. The luminescent properties of the complexes in the solid state have also been studied. |
